Well, for me direct mailing rules.
Another thing I want you to keep in mind is this. Real estate is always good to invest in, but you have to be aware of what stage of the cycle it is in. It doesn't always go up as people like to think, when the real estate cycle is in a downward phase, in some markets houses actually lose value. You must know what phase your local market is in before you buy any house or apartment. For example, in San Diego right now, appreciation is plummeting ... but you can still make money. While the market's tanking you have to stick with buying junkers super cheap from banks and wholesaling them to investors. That the only place where there is demand, among investors, and it's where you can keep your risk to a minimum so that's where you focus. Forget rehabbing or holding anything until the market recovers.
There's a fantastic research tool so you can know where your market is and make the right moves. Check it out.
